COFFEE-ROASTER.

The Schedule referred to in these Letters Patent and making-part of thesanne.

To all whom it may concern Be it known that I, J AMES GALLOWAY, ofChetopall, in `the county of Labette, and State of Kansas, have inventeda new and lisefnllmprovement in Burning and Making Oo'ee; and I dohereby declare that `the following is a full7 clear, and exactdescription "thereof, which will enable others skilled inthe art to makeand use the same, reference being had tothe accompanying drawing,forming part of this specification.-v

This invention relates to a new and useful improvement in the .method ofpreparing coffee, whereby lunch time'is saved, the entire aroma ispresewed, and the extraction ofthe coffee-berry ismore complete than byany method heretofore devised; and

The invention consists in snbj ecting the coffee-berry to the action ofh'eat in water, under pressure, as will be hereinafter more fullydescribed.

The accompanying drawing represents a View of a vessel by'ivl1ich'I amenabled to carry out my invention; but I do not conne myself to anyparticular It is only necessary that the requisite quantity of coii'eeand water, and be surficiently strong to withstand the requisitepressure.

The vessel shown in the drawing is a hollow globe, A, with an aperture,which is closed from the inside by a plate,'B, provided with a brace, C,and screw and nntD. i

'lheplateis tightly fitted or packed, so that there shall-be no leakaget'romthe vessel after the coffee and water have been placed therein, asseen in the drawing where the vside of the vessel is broken away.

Eis the handle, to which a thermometer, F, is attached, si) that thetemperature may be correctly indic-ated.

Gr is a faucet, attached to the lower portion of the vessel, for drawingoff theextract. When the vessel is properly iilled, it is placed over afire, (on a stove or otherwise,) and the temperature is raised to, say,340o Fahrenheit, when ten or iifteeu minutes sutlices to extract all thevaluable qualities of ythe berry. VShould the heat be less than thatnamed,

more time is required for a perfect operation.

By this arrangement there is no loss of aroma, as in ordinary roasting,4while the entire valuable qualities' of the berry are extracted.

A very great saving in the quantity of coffee-berry used is thussecured, while the quality and flavor ol' the extract is greatlyimproved. Raw coiee browns .at a temperature of about 280O Iiahrenheit,but at that degree'of heat the process of browning and extracting issomewhat prolonged.

From practice I havepfound that a temperature of about 3400 Fahrenheitis best calculated for the purpose, as the coffee is browned and theextract obtained in a very short space of time.

-For the purpose of rendering the use of the roaster perfectly safe, asafety-valve or fusible plug, of metal, may be applied in any suitablemanner, or as seen at H.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- Browning andobtaining the extract of coffee by subjecting the raw coffee-berry toheat when immersed in water, substantially in the manner described.
